What causes a woman to have a hydatidiform mole?

A hydatidiform mole may be caused by an abnormality in the process of sperm and egg combination, which leads to abnormal development of the placental villi. If a hydatidiform mole is diagnosed, you need to seek medical treatment as soon as possible to prevent complications.

Hydatidiform mole is an abnormal disease related to pregnancy. It is not the development of a normal fetus, but is caused by abnormal genetic material of the fertilized egg, such as problems with the chromosomes of the sperm or egg, or two sperm entering an egg at the same time, which leads to abnormal proliferation of villous tissue and forms a vesicular structure similar to a bunch of grapes. In most cases, hydatidiform mole is divided into two types: complete and partial.

Complete hydatidiform mole has no normal embryonic tissue and usually develops from a fertilized egg containing only paternal genetic material, which manifests as a rapidly enlarged uterus and abnormally elevated progesterone. Partial hydatidiform mole may have some embryonic tissue, but these tissues usually cannot grow normally and may cause miscarriage due to chromosomal abnormalities. If not intervened in time, hydatidiform mole may cause serious complications, such as heavy bleeding or malignant changes.

To reduce the risk of hydatidiform mole, it is particularly important to pay attention to physical examinations and health management when preparing for pregnancy. Increase nutritional intake, supplement folic acid and vitamins, and try to avoid advanced pregnancy. If you have had a hydatidiform mole before, it is recommended to consult a doctor in detail before getting pregnant again, and do ultrasound monitoring and regular prenatal checkups during pregnancy. If you feel abnormal pregnancy symptoms, such as severe morning sickness, abnormal vaginal bleeding, etc., you should contact a professional medical institution for examination and treatment as soon as possible.
